Thai maths whizzes win 19 gold medals in India

[klauskunkel]

As an amateur philosopher I've pondered that aspects humanity are not on a continuum but very distinctly stratified.

I draw much of this from TV posts.

I'm not sure about that.

A relevant example might be delusions of racial or ethnic superiority. Superficially, we might think that people are either afflicted with them or not.

But there is a continuum involved: people hold with these types of views to various degrees, some quite extreme, while the wiser amongst us might have been able to just about move on from them all together.

So the more I refrain from posting, the wiser I appear...

...but if I refrain, then you wouldn't know about my apparent sagacity...

a paradox for sure, wonder if there is an equation to define this self-defeating conundrum

No, but there are many brilliant Indians. The fact that they could win against the Indians is a real accomplishment. I think many Indians are even smarter than many Chinese. The Chinese may be more cunning and more clever in business. But, many Indians are very sharp. Indians make a real mark on the world stage.

Yeah..there are a few brilliant Indians in a country of 1+ billion.

A few? They have one of the most fertile genetic brain stocks of any country on earth. The richness of their intellects cannot be over stated. I would like to see you go up against the average Indian, who was educated, and spoke good english, head to head in an intellectual competition. Any of us for that matter. Do not underestimate the Indian people. I have lived and worked there, and they are impressive.

WIZMIC is not the only math olympiad that Thailand students were competitors. There seems to be as many math olympiads as there are countries that will sponsor math competition. And contestants are usually from an educational school segment such as Elementary, Primary and High School. The WIZMIC was for primary students.

For example:

In July 2014 there was the Korea International Mathematics Competitions (KIMC) for elementary school level and also the Invitational World Youth Mathematics Inter-cities Competition (IWYMIC) for high school level with a total 31 countries participating: Australia, Brunei, Bulgaria, Canada, China, Cyprus, Hong Kong, India, Indonesia, Iran, Japan, Kazakhstan, Macau, Malaysia, Mexico, Mongolia, Nepal, Netherland, Nigeria, Philippines, Romania, Russia, Singapore, South Africa, South Korea, Sri Lanka, Taiwan, Thailand, Uzbekistan, Vietnam and Zimbabwe.

In Singapore, there was the 2014 International Mathematics Contest (SIMC) involving 11 countries: China, Philippine, Malaysia, Taiwan, Indonesia, Singapore, South Korea, Thailand, Iran, Myanmar, and India.

In China there was the 11th China Southeast Mathematical Olympiad (CSMO) involving 12 countries: the Philippines, China, Hong Kong, Macau, India, Indonesia, Kazakhstan, Malaysia, Mongolia, Singapore, Thailand and the US.

Thailand students did not place consistently as high as they did in WIZMIC.

Well there maths is better than yours, come on what is 4,8000.

Why is it whenever I go into a mom and pop store they look at me like Steven Hawking for giving them the correct money, before they have even finished messing around with the calculator then?

Must be a huge drop between these cleaver kids and the average Thai child........

Or giving them the extra baht with your note, so that you make changing it easy for them?

Most Asians, at least in Primary, learn arithmetic by the Vedic method. It seems impressive at first but is nothing more than a series of magic tricks learnt by rote memorisation. They can take nothing from it forward to algebra, such as multiplication as addition, associative or distributive laws etc. That's why most Thai mattayom students can't do basic algebra!

These competitions are the same in that they comprise questions for which the method is practiced parrot-fashion. The questions may again look impressive but they all involve a series of steps to get the answer if you don't understand what you're trying to do; rote memorised daily over a period of months.

Sorry I think you a stoopid fellow.

WIZMIC 2009

1. In a math contest with three problems, problem A was attempted by 67 pupils; problem B by 46 pupils and problem C by 40 pupils, 28 pupils attempted problem A and B ; 8 attempted problem B and C ; 26 attempted problem A and C and 1 attempted all problems. Find the number of pupils who attempted only problem C.

2. Two dials O and P have pointers that start together from the vertical position. Pointer O rotates counterclockwise at rate of 5 degrees per second and pointer P rotate clockwise at rate 9 degrees per second. How many complete revolutions will P have made when O completes 135 complete revolutions?

3. There are 2009 students from a long line. The first student call out the number 1. Each other student in turn call out a number according to the following rules ; “If the preceding student calls out a one-digit number, this student call out the sum of that one-digit number and 7. If the preceding student calls out a two–digit number, this student calls out the sum of the units’ digit of that two-digit number and 4” What number does the last student call out?

4. In an examination of 60 questions, the final score is calculated by subtracting twice the number of wrong answers from the total number of correct answers. If a player attempted all questions and received a final score of 48, How many wrong answers did he give?

5. The perimeter of the geometric figure below is 304 cm. Find its area, in cm^2

6. Six cubes, each having 5 cm long edge, are fastened together, as shown. Find the total surface area, in cm^2, including the top, bottom and sides.

8. Two boxes contain balls. In the first box there are only black balls, in the second box there are only white balls, so that the number of the black balls equals 15/17 of the white balls. If we take out 3/7 of the black balls and 2/5 from the white balls, then the number of balls remaining in the first box becomes less than 1000, and the number of the balls remaining in the second box becomes more than 1000. How many black balls were there in the first box at the start?

9. Using the digits 1,2 and 3 to form all the possible four digit numbers. For example; 2311 and 1113 are two of them. How many of these numbers are divisible by 3?

13 A positive integer n is said to be decreasing if, by reversing the digits of n, we get an integer smaller than n. For example, 9002 is decreasing because, by reversing the digits of 9002, we get 2009, which is smaller than 9002. How many four-digit positive integer are decreasing?

14. Each side of a triangle ABC is tended as shown on figure such that BK = 1/3AB, CL = 1/4BC, AM + 1/5CA The area of the triangle LKM is 357 cm^2. What is the area of the triangle ABC in cm^2?

15. Using the digits 1 to 9 once each, nine-digit numbers are formed, such as no digit is immediately between two larger digits. How many of such nine-digit numbers are there?

Would it kill you guys to look at this little story and feel good for the students who did so well, representing their schools and their country? No, you have to crap all over it, say it means nothing, and blah blah blah. Are any of you distinguished enough in any way, that gives you the moral authority to disparage these kids? Have another Leo, and give your Nobel laureate brains a rest.

Well done, students. Best of luck to you all. We are proud of you.

Indeed, well said and well done kids! Maths isn't fashionable these days and good on those having a go.

[thailiketoo]

I seriously applaud the achievements of the winners. Excellence in maths/physics in Asia is frequently held up to compare the flagging results of USA.

The sad thing is , that however high the ratings of scholastic achievement in Asia, what appears to be a lack of imagination prevents them from

inventing/creating anything significant.

Whenever there is a scientific/medical breakthrough e.g. yesterday's announcement of a spinal chord repair was a Polish/British achievement.(using olfactory nose cells)

I would change places if I were Apple's 84 million dollar (this years bonus/salary) CEO with any of these guys.

This is not a racist thing, but the few Chinese Nobel prize winners were born in China but resident in US

The Japanese are the exception.

Greatest number of Nobel Prizes..try wiki, u won't be surprised.

I'm a prize winner at guessing people's education level. I'd say yours is sub college.

Most people who go on about nationalities being bright or creative or intelligent or well educated rarely have an education themselves.

Well done kids and I hope the people with the B.A.R. degrees don't get them down.

Right some of these questions require algebra that is above primary level. Problem # 4 for example:

Let x = number of wrong answers.

Let (60 - x) = number of correct answers.

So (60-x) - 2x = 48

-3x = -12

x = 4 wrong answers

Check 56 - 8 = 48
